“Rear end unstable. Vehicle backend swerves and fishtails on wet or icy surfaces. Repair shop states back end is frozen and unable to align rear tires causing vehicle to swerve when driven on wet or icy surfaces. Misalignment of rear results in new tires having to be purchased approximately every 2-3 months.”
NHTSA complaint #10369585, filed 2010-12, 210,500 miles“Pulls to the right when accerating at highway speeds. From 2000 miles -4000 pulled to right at all speeds. Now only highway.Mitsubishi claims this pulling is normal torque steer . ( so was the ford pinto's gas tank problems) if you are not prepared for the pull you will go off the road or into the next lane.I am always compensating and the degree of pull changes with the amount of acceleration. Unpredictable and dangerous . Please call me for further details as to Mitsubishi's response to this. I have spoken to others with same year vehicle who have same problem.”
